This atmospheric river of moisture is not a new phenomenon, but its name is, having been adopted into the meteorology canon after being first proposed in 1994.

Scripps Institution of Oceanography explains the weather phenomenon from the Pacific Ocean that can wreak havoc across California.

An atmospheric river that affects the West Coast—and California in particular—is usually nicknamed a Pineapple Express since the source of the tropical moisture is the area around Hawaii.

Like an actual river on land, an atmospheric river is a large, narrow, and continuous band of moisture, in most cases originating from tropical latitudes where moisture is more readily available.

According to Porter, this atmospheric river will be "unusually potent" and moisture-laden. The tropical moisture being dumped on the East Coast has travelled some 2,000 miles from the Caribbean Sea.
